以下是在 CentOS 系统上直接安装 MongoDB 4.0.25 的详细步骤：

步骤 1：配置 MongoDB 官方源

使用文本编辑器创建 mongodb-org-4.0.repo 文件：
bash 复制代码
```
sudo vi /etc/yum.repos.d/mongodb-org-4.0.repo
```

添加以下内容：

ini 复制代码

[mongodb-org-4.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc

保存并退出文件。

步骤 2：安装 MongoDB

安装指定版本的 MongoDB：

bash 复制代码

sudo yum install -y mongodb-org-4.0.25

c 复制代码

[root@localhost ~]# sudo yum install -y mongodb-org-4.0.25

步骤 3：启动 MongoDB 服务

启动 MongoDB：
bash 复制代码
```
sudo systemctl start mongod
```
设置开机自动启动：
bash 复制代码
```
sudo systemctl enable mongod
```

检查 MongoDB 服务状态：

bash 复制代码

sudo systemctl status mongod

c 复制代码

步骤 4：验证安装

使用 MongoDB 客户端连接：

bash 复制代码

mongo

c 复制代码

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).

The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

检查版本：
bash 复制代码
```
db.version()

```

步骤 5：可选配置

默认配置文件路径 ：
/etc/mongod.conf

c 复制代码

[root@localhost ~]# cd /etc/
[root@localhost etc]# cat mongod.conf 
# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

# Where and how to store data.
storage:
  dbPath: /var/lib/mongo
  journal:
    enabled: true
#  engine:
#  mmapv1:
#  wiredTiger:

# how the process runs
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile
  timeZoneInfo: /usr/share/zoneinfo

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.


#security:

#operationProfiling:

#sharding:

## Enterprise-Only Options

#auditLog:

#snmp:

编辑配置文件（如修改监听端口或数据存储路径）：
bash 复制代码
```
sudo vi /etc/mongod.conf
```
- 修改数据目录：
  yaml 复制代码
```
storage:
  dbPath: /var/lib/mongo
```
- 修改监听端口：
  yaml 复制代码
```
net:
  port: 27017
  bindIp: 0.0.0.0
```
保存后重启服务：
bash 复制代码
```
sudo systemctl restart mongod
```

注意事项

默认数据目录 ：/var/lib/mongo
默认日志目录 ：/var/log/mongodb
默认监听端口 ：27017

如需更改这些路径，请在 /etc/mongod.conf 中编辑并保存后重启服务。

这样就可以在 CentOS 上安装 MongoDB 4.0.25 并运行！
